  • I ported SDK decoder to a mips alike CPU, 120Mhz, I did some optimization based on the CPU ISA, but the decompression speed is still poor, 512KB/s.
    Besides the defined flags, like LZMA_LOC_OPT, what else can I do to improve the decoding speed? I can even sacrifice some compression ratio for better decoding speed, thanks for any help.
